I can think of at least two ways (might be more) to detect conditions on your LAN. But not without a lot of work, and also a lot of overhead. READ: impractical. So, generally, shouldn't be detectable. Don't know what is up on your system. Oh, and you mentioned your dual-band router. But, that's not all of your hardware. The NIC on your console also counts. So do the ports on the router. So does your cable. Something as simple as a bad solder, or a cable that was crimped can also be factors.
